' fFirst, it Twill be iinderstoodthat Vthe turning crank .37 vis preferably detachable VAand is adapted tot they operatinggear stnd v36,V

sired.

fries 'the operating gear rotatably mounted therein, is itself' adaptedto angularly turn Within the bore 21 provided therefor in the fixed cover plate 190i the casing member 15v and in doing so permits the operating gear 33, Which'is carried thereby, to engage Witheither oneor the .other ofthe gears 42 or 53, and that said eccentricfdisc 25' maybe lock-edinto engaging position With`V either. of said Ygears v42 or' 53, yas. the case may befand according Vas may be desired, Y'

through the locking finger 30.

Thus, if it is desired to operate the clampiscrew 50, the operating gear is shifted vto mesh With the clamp-screW-gear'53, as shown l in Fig. 6,; andy the locking, member 30jis any siiitable j'nianner, as :by means'v or. the retaining studr45' shown in said Fig. 3;

turning of the operatinggear :'33, 4through the'turning of'thecranlr37 when said oper` atlngzgear is so lset Withveither of saidv gears 42 or 53, Will rotate theselectedgear according tothedirection otrotation of said turning crank r37. So that it Will `be Lunderstood that the :turning ot, the jackscreW-gear 42v in one direction or thel other will `either eed thejack-screw 40 in or-out of the casing meinber 15, according as may be desired, and also that the turning ofthe clamping-screw 5.0 in one directionor the other Will'causethe traveling blockz `to move along said clamping-'screw in one direction or the other, according as may be de- Thus Will be understood thatthe tool lis detachably coupled with the rirntogbe han,- dled thereby by means of the vpairV of *gripping jaws land 57 which engage and gripy the opposite flanges of thefrim on either side ofthe split ljoint thereof, as shown in Fig. 1.

."ItY will be herenoted that itis preferredA (Without being limitedlthereto) .to make the casing supported, gripping jaws 61 shorter than the anchoring j'aws'57, .Whichfare-supL ported on 'the movable block 55, for bringing the jack-screw vsocket kv17k of the ycasing member l5 nearer to the vrimfll, as shown ink Fig.V 1; yIt' is also preferableto position said shorter gripping jaws nearer to the split 12 of the-rim,"as vshown inisaidFigrl.

,With the gripping jaws of the Vdevice thus secured t0 i the rim, the `device -inay` then .be monipulated according as `the" particular" needs of the rinii'nay require, depending upon the'type'of joint'of the particular rirn. Y

If the rim vhas the s o-ca'lled Vinterlocking joint the first operation would be to expand the rim, which may be accomplished b"yreey ACil' j erating gear with the gear 53,as shown. in Fig-$16,.` and'turning the crankjjin the" vdirection touiteed-thescrew 5l0yso that said' block 5 rwould be'forcedto move towards' the end of said clamping Vmember 6G', as* f suggested. `With 1 the spread open, the-nextjoperation; of the" tool ywould, ,beil to `:cause fthejend *of Ying the jack-screwed from the rim and causing i the' Vmovablefbloclif ,f 55` to g move towards thefoiiter and. projecting end ofthe fizlaiifip-gv Ying-screw'. 50. This. spreadingjoriexpansion yieatii're would, result from engagingr the 'op` the rim` engagingfthe short, gripping j aw of vthe tool .tof overlap they .other end yof. the rim. 'Io do vso ktheoperatingv gear 33- shouldbef-shiftedto theengaging A:position withthe jack-screw-gear(shown in Figsgl i and 3, andithen'theiturning crank` 37 should be turned-tolbring the'jack-scre'w 4:0

shift the .operatinggear to engagewith the@ clamping-screwgear and turn the crank 37, this time'to cause the movable blo'el`55j to approach the casingfl member-l5. *The tool 'in this contractingv operationwill con*- 1 tractthe rim and allowforthe ready and easy removal of the tire 10 therefrom.l ln a; similar manner'rit will be'understood 'that the rim maybe replaced'f'with the tire again, and anytype of split rim lmay thus be;

' It will be here observed that the gears Aused in the devicea'repreferably beveled as Vthe miter gears shown, and thata the arrangement of the same in the device kallows theV crank-lever 37 to bev Voperatedy substanrtially in the plane of the rimandftire, and
